[SOLVED] unknown to this version of the J-Link software ?

I am working normally on ezr32lg, i am flashing and debugging throw JLink.
Now, i am working with an efr32mg, the JLink said this, when i trying to flash it :

""Target connection not established yet but required for command.
The selected device "EFR32MG---" is unknown to this version of the J-Link software.

Please make sure that at least the core J-Link shall connect to, is selected.
Proper device selection is required to use the J-Link internal flash loaders
for flash download or unlimited flash breakpoints.

For some devices which require a special handling, selection of the correct device is important.
No valid device has been selected.

Thank you for your inquiry.
What software are you using for flashing the target device?
What J-Link software version are you currently running?

The selected device "EFR32MG---" is unknown to this version of the J-Link software.

You have to specify the exact target name. If you do not know it you can enter "?". Then you will get a list with all supported devices and there you can select the device you are looking for.
Make sure the device you are trying to debug is actually supported by J-Link. A list with all currently supported devices can be found here: https://www.segger.com/downloads/supported-devices.php

Do you advise me to update the Jlink ?
If, yes how please ?

We usually recommend to use the latest software version as we constantly improve our software and add new features.
But if you have a stable programming setup running you can stay with the version you are comfortable with.
To update to the latest version visit: https://www.segger.com/downloads/jlink/#…cumentationPack

There you can simply download the latest debian install package and install it.
